Obs EUM present er am unable to refer this imperfect 
portion of a cephalon to any definite genus. The published 
figure does not convey a correct idea of the anterior outline, 
wide concave area, anterior to the glabella, as in many 
other Trilobites; this alters the whole aspect of the specimen. 
There are ET two pairs of furrows, instead of three, as I said 
in my former description, the basal pair complete and ex- 
tending across the glabella, and an anterior pair very faintly 
marked, mere ''nicks," in the axial furrows. 
is imperfect ped may be, as suggested by Mr. F. 
Chapman, an example of his Ptychoparia thielet, but before 
adopting | eae suggestion I prefer to await additional and more 
erfect rial.
